Tool use in birds
Skoumalová, Žaneta ; Exnerová, Alice (advisor) ; Nekovářová, Tereza (referee)
Tool use has been observed in many bird taxa, mostly in parrots and songbirds. Tools are primarily used for a purpose of food acquisition and food preparation and physical maintenance. Spontaneous tool manufacture or tool use has been observed in species, which do not use tools in the wild. Tool using is actively performed only by those birds, whose natural environment has a reduced food availability, food is difficult to extract and handle. Tool manufacturing and tool using requires a considerable degree of cognitive abilities, which are experimentally tested in tasks involving use of tools. Differences between species that use tools in the wild, and those that do not are manifested not only in solving experimental tasks, but also in how birds acquire the ability to use tools. While tool users often solve tasks successfully by using causal reasoning, non-tool users are not always capable of solving complex tasks and understanding of the physical properties of the situation. Negative results of these species do not necessarily imply a lack of understanding, but they can also be caused by morphological or environmental constrains, which make tool use more difficult. Tool users also have inherited behavioral patterns, which are further strengthened by individual learning and can be influenced by...

Mediated training as a possibility for socially disadvantaged students
Škopková, Pavla ; Krykorková, Hana (advisor) ; Běhalová, Andrea (referee)
This Master thesis aims to solve the question of developmentally-creative possibilities in the schooling process. This question is contextualized education of socially disadvantaged pupils. Because in shaping the learning competencies, this area is not developed enough and specific methods are somewhat rigid, it will be introduced one of the option how to to develop learning skills and abilities of the pupils , and which are in the teaching competencies deemed as essential. In this context will be introduced stimulatory and intervention program of Instrumental Enrichment as a concrete form of execution of Mediated learning and also as an effort of perspective innovation of curriculum. With the intention to point out the limitless possibilities of developing pupil's learning potential, the text focuses on the theoretical and conceptual bases, which constitute the entire program. The program is the instrumental set of tools that lead to the activation of cognitive structures and their subsequent enrichment. Therefore, except the theoretical foundations are also presented cognitive strategies metacognitive training that simplify cognitive modifiability, and that lead to the development of pupils' learning potential.

Linguistic picture of the particular somatisms in Czech
Škanderová, Adéla ; Janovec, Ladislav (advisor) ; Chejnová, Pavla (referee)
The bachelor thesis deals with a lingvistic picture of the world of the particular somatisms, namely the components of the digestive system (stomach, bile, gall bladder, heartburn, intestine). The theoretical part covers the term cognition, cognitive science and, logically, cognitive linguistics. Furthermore, it includes the indispensable and key topics which have to be taken into account to understand the concept of the linguistic picture of the world, i.e. conceptualization, categorization, metaphor, anthropocentrism etc. The practical part is interested in the real occurence of the somatisms in various language contexts. In particular, their occurence in collocations, phraseology and idiomatic expressions. The analysis is based on the profile theory and its image schema. The lingustic backround is supplemented with the psychosomatic knowledge because it appears to be a helpful science branch while completing and considering the possible connection between the occurence of somatism in the language of the specific culture and extralinguistic reality.

Biological determinations of cognitive disorders
Vítek, Petr ; Šivicová, Gabriela (advisor) ; Stehlík, Luděk (referee)
As a topic of my bachelor thesis I have chosen "Biological determinants of cognitive disorders". Because of the bachelor thesis' coverage I was forced to choose only two cognitive functions - memory and thinking. This work as a whole is an attempt to combine psychological theories with neurological and psychiatric knowledge which are now popular thanks to the rapid development of imaging techniques of brain. One chapter is specifically focused on their brief summary. In the beginning specific cognitive functions are circumscribed but only two of them are taken further - memory and thinking. More space is dedicated to memory because neurological research of memory is much more complex compared to thinking. My approach is similar in both cognitive functions - at first I focus on description of normal functioning and then I classify and describe specific disorders, trying to find their neurological correlations. The second part of my bachelor thesis proposes the research of episodic memory, in which I would compare differences in its distortions from both neurological and neuropsychological perspective. Patients with delusions, pseudologia fantastica and patients with often confabulations are the target group. I tried to create as realistic design as possible. However I realize its financial...

Metaphor as a Tool for Communication and Creative Thought
Policar, Antonín ; Kulka, Tomáš (advisor) ; Stejskal, Jakub (referee)
This work is concerned with the role of metaphor in language, discourse and thought. The first section presents a brief historical survey of the origins and development of theorizing about the metaphor as a legitimate cognitive tool and not just a rhetorically or poetically effective but otherwise uninformative sort of expression. The aim of the second section is to outline several different accounts of metaphor given by contemporary researchers in the fields of the philosophy of language, congnitive psychology and linguistics as well as to hint at some possible ways they could be interconnected. Especially those theories are concerned which in some way diverge from the traditional view on metaphor as a fringe phenomenon of language and discourse and which on the contrary stress its central role in the meaning- making activity of the human mind. Although the work does not focus primarly on the metaphor in art, its relevance for aesthetics lies nevertheless in its highlighting certain aesthetic or poetic aspects of human reasoning and everyday communication.

The influence of corticosterone and corticoliberin on damage of the hippocampus and their relation to cognition
Řezáčová, Lenka ; Mareš, Pavel (advisor) ; Mejsnar, Jiří (referee) ; Šusta, Marek (referee)
Dissertation "The influence of corticosterone and corticoliberin on damage of the hippocampus and their relation to cognition" deals with the cognitive, behavioral and histological changes in experimental rat strain long-evans that closer describe the consequences of long-term continuous application of corticoliberin and/or corticosterone. Testing of the behavioral changes was divided into two phases. The first one - within three or fourweeks respectively administration of these hormones, therefore until their early effects - and the second phase - after four weeks of completion of the first phase at the time of the possible late effects. In the twelfth week the experimental animals were killed and in the group which had exogenously elevated corticosterone, the morphological changes in the hippocampus were monitored and measured. In all experimental groups alteration of behavior was observed. Histological and morphological changes in the brain we have found. Layout of experiments in two testing phases allowed differentiation of the early changes and the late and persistent changes. The arrangement of experiments allowed the choice of tests to compare not only individual effects of both hormones (corticoliberin and corticosterone) but also their coactioning and biological responses to them. Using a wider...

Cognition test for testing object permanence in birds and primates
Marhounová, Lucie ; Landová, Eva (advisor) ; Veselý, Petr (referee)
Object permanence is a cognitive ability to mentally represent the existence and the movement of hidden objects. This phenomenon is being developed since birth in six different stages following the development of the sensorimotor intelligence. Not only the humans but also the other animals possess a certain notion of hidden objects and acquire various degrees of this ability depending on their life strategies. This thesis summarizes the research conducted up to the present in the field of the object permanence within the infant developmental psychology, but particularly in the animal world with the emphasis on the taxa where this ability has been most researched, that is in primates and birds. This thesis also recapitulates the types of the cognitive tasks used in the object permanence research and compares the methods of experiments applied to the humans, the primates and the birds. Part of this thesis also involves a phylogenetic reconstruction estimate of the ancestral character status in terms of the object permanence and testing the progress dependance of such character in relation to the selected ecological factors in primates.

Testing traits Saarloos wolfdog and Czechoslovakian wolfdog
Peterová, Dalia ; Fiala Šebková, Naděžda (advisor) ; Jana, Jana (referee)
This thesis is about cognitive behavior of dogs and wolves. It focuses on breeds of Czechoslovakian Wolfdog and Saarlooswolfdog, resulting from crossbreeding of a dog and a wolf. The thesis describes their natural behavior and abilities to cooperate and communicate with humans.
The thesis repeats series of behavioral experiments performed on dogs and wolfs described by Ádám Miklósi in his study from 2003 "A Simple Reason for a Big Difference: Wolves Do Not Look Back at Humans, but Dogs Do". We were interested to know how these particular crossbreeds would behave in the same model situations, thus we tested them on the Czechoslovakian Wolfdogs and Saarlooswolfdogs.
The first study shows whether the subjects are able to locate hidden food indicated by a known gesture of a human experimenter. The second study examines whether the subject, that is not able to solve a similarly looking task by itself, looks at a human for clues. The dog easily learns how to solve a simple task: opening an object to get to food. And it subsequently faces a similar situation, in which, it is impossible for the dog to resolve it by itself.
These experiments demonstrate that Czechoslovakian Wolfdog and Saarlooswolfdog are able to collaborate with humans with similar willingness. There is no statistical difference between these two breeds and the two sexes of these animals.
